Associated View Custom Button

Hello everyone,

I have a third party grid and I would like to add a button which open the associated view of the record. In my case the associated view between Account and Opportunity.

I already add the image:

<img class="ui-button" id="createOpportunity"  onclick="openAssociatedView()" src="../webresources/aut_associatedview.gif">

But I don't what to write in my function openAssociatedView(). My button should have the same action as the button represented by:

Do you have any idea?

Thanks a lot.
